        全局定义是指在全局定义里的标签缺省下的样式规则，包括三部分：<br>
        1、HTML5新模板和兼容：包括十二个block新标签、三个inline-block新标签，以及隐藏等其他属性；<br>
        2、全局标记一致性定义：约定html、body、img、p等标签在所有浏览器中一致性定义；<br>
        3、表单一致性定义：约定button、input、checkbox、radio等表单属性在所有浏览器中一致性定义。<br>

为防止主流浏览器中，显示"不带控制按钮的音频模块"这一问题。以及解决iOS5移动端显示多余高度的兼容性问题。

    html {
        font-size:204.8px
    }

html,body{width:100%;height:100%;position:relative;overflow:hidden;}

1、设置全局字体，防止一些设备上字体随屏幕放大而改变字体大小,如webkit的Safari
2、指定文档宽高并隐藏超出
3、当屏幕横坚切换时字体大小调整和以前一样
4、文档字体大小以rem为主，所以用@media screen自定义不同的html字体大小
